Code

<ImageView
            android:id = "@+id/imageView"
            android:layout_width = "wrap_content"
            android:layout_height = "wrap_content" />

        ImageView imageView = findViewById(R.id.imageView);

        RequestOptions options = new RequestOptions()
                .placeholder(R.drawable.ic_launcher_background)
                .error(R.drawable.ic_launcher_background);

        Glide.with(this).load("https://www.tutorialspoint.com/images/tp-logo-diamond.png").apply(options).into(imageView);

`imageView` is clearly null. *Why* is unclear. Can you post a [minimal, reproducible example](https://stackoverflow.com/help/minimal-reproducible-example)? — Joachim Sauer, Aug 30 '21 at 17:18
@Lav Sharma please use like https://stackoverflow.com/a/44199289/12660050 options put into apply directly... — Vatsal Dholakiya, Aug 30 '21 at 17:49
@VatsalDholakiya: well, the stack trace is cleary says "Argument must not be null" and the method you call is `RequestBuilder.into` and if you check the [RequestBuilder source](https://github.com/bumptech/glide/blob/master/library/src/main/java/com/bumptech/glide/RequestBuilder.java) then you'll see that the first thing that `into()` does is call `Preconditions.checkNotNull(view);`. I'm very confident that the value that you pass to `into()` is null for some reason. You can chose to not believe that, but that doesn't mean I'm wrong. — Joachim Sauer, Aug 30 '21 at 18:23
Yes, it is null pointer exception you are right that there is null at into() but not because of nothing there is pass. I think It is because of something wrong in options which is passed in apply(). — Vatsal Dholakiya, Aug 30 '21 at 18:32
@VatsalDholakiya: that's not what the code suggests. Why are you so convinced that `imageView` is not `null`? Have you looked at the line in a debugger? Logged the value just before using it? — Joachim Sauer, Aug 30 '21 at 18:34
I am not saying that imageview is not null (May be from link image is not fetching. )I am saying that imageview is passed in into(). — Vatsal Dholakiya, Aug 30 '21 at 18:37
And to proof my case: I'd bet that you're using version 4.7.0 of Glide, because [that's the version where the `Preconditions.checkNotNull(view)` call is exactly on line 651, as indicated by your stacktrace](https://github.com/bumptech/glide/blob/v4.7.0/library/src/main/java/com/bumptech/glide/RequestBuilder.java#L651). — Joachim Sauer, Aug 30 '21 at 18:37
The problem is the value that you pass to `into()` is null. That value is stored in `imageView`. Therefore `imageView` is `null`. Find out why and fix it. — Joachim Sauer, Aug 30 '21 at 18:38
@VatsalDholakiya [this](https://stackoverflow.com/questions/44198856/glide-does-not-resolve-its-method/44199289#44199289) solved my issue. You can post it as an answer so that I can accept it. — Lav Sharma, Aug 31 '21 at 08:31

Add .apply(new RequestOptions() to continue with latest version. Just Replace below code:

Glide
 .with(this)
 .load(R.drawable.image_default_profile_picture)
 .apply(new RequestOptions()
 .placeholder(R.mipmap.ic_launcher_background)
 .fitCenter())
 .into(imageView);
